The bands are also carried on suitable idler rolls or pulleys 13 suitably disposed and pivoted on said lateral members. Cooperating guides 14 adapted to hold the papers, (as the envelops 15) to be operated on by our mechanism and the typewriter itself, are carried by the respective lateral members and are adapted to guide such papers to the bands under the pressure of the followers 16, spring-pressed for that purpose as shown and having a sliding movement in follower guides-the slots 17 in the guides 14. Each follower has also a slightly rotatable movement on its guide pin 18 when at the rear portion of the slots 17, so that the follower may be thus slightly turned to en gage its part,-the lug 19with a corresponding co-engaging part of the slot,viz., thestop or shoulder 20, thus to hold the follower in its rearward position while papers are being placed in the guides. This follower is so guided as to press the paper-body 21 (viz., the mass of papers held in the guides) against the tangential portion 22 of the band, thus to insure their engagement thereby. These guides 14 are minutely adjustable toward and away from the bands to accommodate papers of different thicknesses and to feed them severally, as by the screws 23 operating to slightly turn such guides on their pivotal mountings 24.

he feeding mechanism is actuated in connection with the rotation of the platen, as by the sprocket chain 25 carried by the sprocket wheel 26 on the platen and by the sprocket wheel 27 on the feed-operating shaft.

To prevent the lifting of the platen relatively to the carriage (as may be done in some typewriters) by the turning of the platen which draws on the rearward portion 42 of the chain, the connected arms 28 are provided, adapted to rock at their free ends relatively to the axes of the platen and the feed-operating shaft respectively, and carrying the chain-engaging roll 2!) as shown. As the drawing tension on the portion 42 of the chain increases, the roll 29 is thereby forced inwardly or forwardly, this straightening the arms to some degree and thereby holding the wheel 26 and the platen from rising. The papers, as the envolops shown, are fed by our mechanism one at a time to the platen, and after being written on by the typewriter, are conveyed by the bands against which they are held by springpressed rolls guides 32 for their edges, and are delivered into a paper holder comprising lateral members 33 carried respectively by the secondary and splined on 31, 43, and through suitable frames lateral members 10. A stop 34, adjustable to accommodate papers of different dimension in the direction of their delivering movement of the paper holder, is adapted to arrest such movement, and is adjusted to a position nearer a portion of the arcuate movement of the band over the uppermost roll 13 than the dimension of the papers in the direction of their delivering movement, so that the lower edge of the papers may, by the engagement of the moving band, be bent backwardly, thus providing an entering space or sufficient clearance 35 for the ready and unobstructed delivery of succeeding papers to the holder. A springpressed retaining member 36 is adapted to retain the paper bcdy 37 in said holder and to yieldingly admit the papers thereto. At the point of the delivery from the band to the paper holder, the papers are (as shown in Fig. 3) deflected from the direction of their previous movement by means of a deflector, (which in the construction shown is the uppermost roll 43), thus insuring their ready introduction into the holder, each successive paper next to the one last introduced.

To readily apply our feeding mechanism to various typewriters, we provide a chuck 38 split to form fingers 39 adapted to receive and hold the end of the platen or its shaft 44. This chuck has a surrounding sleeve 45 whose interior wall is in inclined relation to the fingers. A screw 46 is threaded in the chuck and has a washer 47 holding the bandle 48 in position, and is adapted to move the sleeve longitudinally relatively to the clutch, in order to compress the fingers on the platens shaft. The secondary frames lateral members 10 have T-shaped slots 49, wherein the supporting portions 50 of guides 51 engage; these guides have spring arms 52 and are adapted to be turned in the slots, as shown in dotted lines in Fig. 9, to move them out of the way, etc. The followers 16 being pushed back to and held in the position shown in dotted lines in Fig. 3, papers (as envelop s 15) are placed in the guides 14, whereupon, the follower being released, they are pressed against the bands. The platen being turned, as in the ordinary operation of the typpewriter, that paper which is engaged by the portion 22 of the bands is slipped off from the rest of the paper body 22 and fed to the platen where it is written on by the typewriter: further rotation of the platen carries this paper by the bands, between the guides 32, and delivers it into the paper holder, and at the same time con vcys other papers to the platen, one at a time.
